A Case of Vomiting in a Horse, caused by Invagination 
OF THE SMALL INTESTINE. 
A REMARKABLE case presented itself in a grey mare, of middle 
size, seven years old, and attached to one of the omnibuses. 
When she was led out for examination, it seemed that she had 
laboured under violent colic, which had been aggravated by strong 
doses of sulphuric acid. Her general appearance indicated loss of 
strength, acceleiated breathing, the inspiration short, the nostrils 
much distended, and discharging a green fluid of an acetous smell, 
and mixed with portions of food. The belly distended — not pain- 
ful on pressure — the pulse small, hard, and frequent — the mucous 
surfaces had preserved their natural colour. All these circum- 
stances led us to fear the rupture of some important organ, or the 
indication of some fearful result. 
She was immediately placed under an antiphlogistic course of 
treatment. During the first hour there was considerable vomit- 
ting. The animal discharged both by the nostrils and the mouth 
full two pounds of fluid. The blood which flowed during a bleed- 
ing from the jugular rapidly coagulated. Convulsive contractions 
were observed in all the muscles of the body, and particularly 
about the chest and shoulders. New and considerable quantities 
of food were ejected from the stomach ; and, at length, she laid 
herself down, with her muzzle pressing on the litter. The pros- 
tration of strength more and more increased — her eyes were 
haggard — the vomiting was more frequent — the inspirations also 
became more and more frequent — the pulse could scarcely be felt. 
The animal again and again endeavoured to raise herself, but im- 
mediately fell — and, at length, died about four hours after she 
was received into the hospital. 
Post-mortem Examination an Hour after Death . — There was 
no fluid diffused in the peritoneal cavity. There was rather a 
voluminous intestinal mass, hard to the touch, and being the result 
of many simultaneous invaginations. The central portion of the 
small intestine, at an equal distance from the pylorus and the 
caecum, was strangely doubled, forming several volvuli of such a 
kind that — proceeding from the exterior to the interior — there were 
eight or ten distinct vaginations. It seemed as if there were two
